JOSEPH C. ROTH AND JOHN F. BERRIOK, OF BUFFALO, NEW YORK.

CLOSURE OR STOPPER- FOR BOTTLES OR OTHER REGEPTACLES.

Original application filed June 5, 1912, Serial No. ?'01,779.

To all whom- 2'15 may concern Be it known that we, JOSEPH C. Born andJOHN F. BERRIOK, citizens of the United States. residing at. Buffalo, inthe county of Erie and State of New York, have invented a certain newand useful Improvement in Closures or Stoppers for Bottles or otherReceptacles, of which the following is a specification.

This invention relates to improvements in closures or stoppers forbottles or other receptacles.

The primary object of the invention is to provide a closure, or stopperfor the opening in a bottle or other receptacle which when fitted inplace automatically locks itself therein and can not be removed withoutbreaking the bottle.

This application is a division of an application filed June 5, 1912,Serial No. 701,779 for improvements in non-refillable bottles.

The invention also relates to certain details in the constructionthereof which will be hereinafter described and claimed, reference beinghad to the accompanying drawings in which a preferred embodiment of theinvention is shown.

Figure 1 is a central vertical section through a bottle having theimproved closure or stopper fitted in place in an opening in the bottomthereof. Fig. 2 is a transverse section through the bottle on line 2 2,Fig. 1. Figs. 3 and 4 are details of the self locking mechanism.

In refer-ring to the preferred embodiment of this improvement shown inthe accompanying drawings in detail, like numerals designate like parts.

The body 1 of the bottle, together with the neck 2 are preferably formedin one integral piece of glass or other suitable material. In theembodiment shown, a round opening which is counter-sunk or enlarged atits lower end is formed in the bottom of the bottle as shown in Fig. 1.A closure or stopper which is made of glass or other suitable materialis shaped to fit snugly in the opening and consists of an upper bodyportion 3 which fits within the circular opening and an enlarged bottomflange portion at which fits tightly in the bottom counter-sunk portionof the opening as shown in Fig. 1. To form a tight joint a thin annularwasher 5 is fitted between the annular wall of the opening in the bottleand the circular edge Specification of Letters Patent.

Serial No. 709,386.

of the stopper as shown in Fig. 1; a slight annular groove being formedin the wall of the opening to receive the washer 5 as indicated at 6 inFig. 1. The closure or stopper is automatically locked in place byspring pressed pins which when the stopper is in place are completelyconcealed and protected within the body of the bottle and the stopper asshown in Fig. 1.

Referring to Figs. 1 and 2 it will be noted that a series of radialhorizontal recesses 7 are formed in the outer or peripheral edge of theclosure or stopper and a like series of radial horizontal recesses areformed in the inner surface of the annular wall of the circular openingin the bottom of the bottle body. The recesses in the inner surface ofthe annular wall are indicated by the nu meral S and register exactlywith the recesses 7 when the closure or stopper is properly fitted inthe circular opening in the bottom of the bottle as shown in Fig. 1.

lVhile four of the registering sets of recesses are shown in theaccompanying drawings, it should be understood that more or less may beutilized as desired.

A series of coil springs 9 are arranged within the inner portions of therecesses 7 and press against the inner ends of pins 10 located in theouter portions of said recesses 7 forcing the outer ends of the pinsoutwardly into the recesses 8 as shown in Figs. 1 and 2.

In fitting the closure or stopper in place in the circular opening, thepins 10 are first forced inwardly against the tension of the springs andthen the closure or stopper is placed in the opening and forced inwardlyto the point where the recesses 8 register with the recesses 7 therebypermitting the springs 9 to force the pins 10 outwardly into therecesses 8 and permanently and automatically lock the stopper in placein the opening in the bottle.

It will be observed by referring to Fig. 1, that the slight annulargroove formed in the wall of the opening in which the washer 5 is fittedis located exterior and interior to the enlarged outer countersunkportion and eX- tends inwardly from the inner termination of theenlarged countersunk portion to within a short distance of the recesses.The advantage of this construction is that the forcing of the closure orstopper into place in the opening in the bottle also forces the QLoader? Washer 5 into the groove as the flanged portion of the closureor stopper presses against the outer edge of the washer therebyproducing an absolutely air and Water tight joint.

This improved closure or stopper may be employed in connection with anon-refilling mechanism located in the neck of the bottle as illustratedand described in the parent or original application filed June 5, 1912,Serial No. 70l,779, of which this present application is a division, orit may be differently located or arranged or may be altered modified orchai'iged or some or the parts may be altogether omitted Within thescope of the following "Without departing itroin our in vention.

In some instances it may be considered desirable to utilize theimprovement in various other types of receptacles and containers for thepurpose of securing a permanently sealed package Which cannot be openedWithout breaking the package.

Wi e claim A bottle provided With an opening, the

outer portion of which is enlarged or countersunk, a closure or stoppershaped to fit snugly in said opening and having an in ner body whichfits within the inner portion of the opening and an outer enlargedflanged portion which fits tightly in the enlarged or countersunk outerportion of the opening; the edge of the inner body of the closure orstopper and the surrounding Wall of the inner portion of the openinghaving complementary registering recesses, springs in said recesses,locking pins also located in the recesses and adapted to be forced intolocking position by the springs; the Wall of the opening exterior to therecesses and interior to the enlarged or countersunk portion being inpart slightly enlarged. to provide a narrow annular groove and a thinannular Washer titted in said groove and around the closure or stopper.
